Answer:
Explanation:
When the number of slits increases, the intensity of fringes increases.
So, the fringes appear to be more bright.
As we know that the fringe width is inversely proportional to the number of slits, so as the number of slits increases, the fringe width decreases, hence the fringes are narrower, bright and close together.
Answer:
depends on how big the car is and what force is moving them.
Explanation:
the 3lb box will go slower because it is the lightest. the 10lb box is the 2nd slowest. the car will be smaller than the 18 wheeler on the road. but it has less cargo so it will probably go faster. if you are dropping it, then the 18 wheeler will go faster. but if you are seeing if it will go faster on the ground, the car will because it has less cargo or wheels to weigh it down.
The mass of the ball is 1.55 kg and its change in momentum is 10 kgm/s.
<h3>What is momentum of a body?</h3>
The momentum of a body is the product of the mass and velocity of the body.
- Momentum = mass * velocity
Mass of the ball = momentum/velocity
Mass of the ball = 3.29 / 2.11 = 1.55 kg
The change in momentum of the body or Impulse = force * time
Change in momentum of the body = 5.00 * 2.00 = 10 kgm/s
Therefore, the momentum of a body depends on its mass and velocity.
